Default Haswell VRM

Saw an article, second tier motherboard producers are concerned with migration of motherboard functions to CPU.
As a power supply forum are there any concerns, benefits or problems with VRMs on chip?
It does look like a quality boost if done correctly?
Just speculation

Doubtful load on VRMs will increase, if processors are to be more power efficient, they should about break even with added SB.

I think that drawing traces that will carry data/signals to/from the CPU will be much more of a challenge than making a proper VRM...

Makes me feel I'll pass on early adoption of Haswell.
Usually skip "early adoption" anyway, lol

It's rumored that Haswell will integrate processor VRM on chip package, that is, besides the CPU die, there's a second die including the highly integrated switches and inductors which converts the processor intermediate power (~2.0V) to various voltages (VCC, VCCIO, VCCSA, VCCAXG). A multi-phase VRM on the motherboard will generate a single intermediate power source, instead of the four voltages on current Socket 1155 motherboards. That will greatly simplify the VRM design of Haswell motherboards.
